The Benelli shotguns are recoil inertia operated. Very simple action, easy to clean and extremely fast cycling. I had a M1 tactical with 8 round magazine. It was stated in the owners manual that you can fire all 8 rounds before the first shell hits the ground. I could only get seven. It will also fire any commercial load without jamming because they don't rely on gas pressure to cycle. I have mixed the loads in mine. Eight different loads from 2" low base 8s to a 3" slug in the tube and I rapidly fired all of them with out a problem. The only draw back I can see to a Benelli is the price.

To save the world from stupid people remove all warning labels and let nature take it's course.
